The Fiscal Tax Year officially begins July 1st and ends June 30th.
The next property tax installment is due 11/1/2015 (late after 12/10/15).
New tax bills are are normally mailed in October.

My own assessment has increased 9.77% for the new fiscal year.
This is after increasing 11% for the prior fiscal year and 10% the year before that.
Normally, Prop 13 caps property tax assessment increases to 2% annually.
